OIL-BURNING ATTACHMENT.

Application filed April 15, 1921, Serial No. 461,515. Renewed April 5, 1923.

To all whom it may concern:

Be it known that we, ACHILLE'KAISERMAN and ALBERT ZAUGG, citizens of Switzerland, and residents of Detroit, in the county of 6 Wayne and State of Michigan, have invented a newand Improved QiLBurning Attachment, of which the following is a description.

Our invention relates to oil-burning means employing steam to atomize the oil or heavy hydrocarbon being burned and more particularly relates to an attachment designed to' v. be employed in connection with the steam vboiler of a heating system, a hot-air furnace orthe like. I

The general. object of the invention is to provide an efiicient attachment of. theindicated class and constructed and arranged with a view to promote convenience in in:

stallation, operation and-repair. Y

. The distinctive features will appear from the specific description of practical embodiments of the invention as hereinafter given.

Reference is to be had to the accompany-- 7 ing drawings forming apart of this's'pecification, it being understood that the drawings are merely illustrative of practical em; bodiments of the inventiom a Figure 1 is a side elevation of a burner attachment embodying myinvention illustratingthe same in connection with.a heat-v ing furnace shown partly broken away and in section; J i

Figure 13 is a vertical section of the gas burner employed 'with the steam generator shown in Figure 9.

Referring at first more particularly to Figures 1 to 7, the burner proper 15 is adapted to receive oil in a manner hereinafter described from an overhead oil tank 16, the outlet pipe 17 of which discharges to a filter 18 from which the oil passes upwardly through a-standard 18 and pipe 18 to a reservoir, 18. Water is supplied from 'an overhead tank 19', the discharge pipe 20 of which is'supported on the standard 18 by a clamp 20, said pipe delivering to the inlet 21. at the depending distributing at- 1 tachment 22 of an annular double-wall steam generator 23 froni'which steam rises into a dome 24. The steam passes from the dome 24 in a manner hereinafter referred to, to a steam pipe 25 which connectswith the upper end of a steam coil 26 in an oil preheater 27 the lower end of the coil connecting with an upwardly returningterminal 26 which discharges steam to a passage 28 leading to the v steam nozzle 29 which is regulated by a manually operated valve 30a The steam "nozzle discharges to a-horizontal mixing tube or venturi 31 in the interior of the steam generator 23. Oil passes of the heater 27 so that oil will flow upwardly outside of the heating "coil 26, 26* and pass laterally inward througlfa discharge pipe 35, leading into the burner 15 provided with an upstanding oil nozzle 34 terminating directly infront of the steam nozzle 29. Y Y

- The steam from the wardly through an outlet pipe at 35., the lower end of which connects withthe steam pipe 25. The lower end of the pipe 35 seats a valve 36, the stem of which is carried by a float 37 in the dome 34, sothat should water rise in the generator 33 and dome 24 the valve 36 will close. Y

dome 24 passes, down from the reservoir 18 through a pipe 32 which connects wi h the lower end In the distributing chamber 22 of generator 23 is the series of concentric partltions 37 having registering outlet holes 38.

The steam nozzle 29 has a flattened outlet and a valve 39 is provided therefor controlling said outlet in the form of a vertical rockable tongue secured to a transverse pin 40 .on a yoke 41 hung as at 42 on a short arm of a lever 43 which is fulcrumed at 44 on the arm 45 of a fitting 46 in the general form of a flanged collar embracing the steam nozzle 29 serving to clamp the nozzle tip in position on a nipple 47 at the interior of the burner body 15 and communicating with the passage 28 subject to the regulation of the valve 30. A lever 43 is suspended by a plate spring 48 made fast as at 49 to the fitting 46 and riveted as at 50 or otherwise secured between its ends to said lever 43. A regulating screw 51 is provided in the fitting 46 to bear against the top of the lever 43 to limit the lever 39 in imparting a movement to valve 39, while a set screw 52 in the ,lever 43 is adapted to bear on the spring 48 adjacent to the fitting 46 and regulates the tension of the spring, thereby .determining the degree of closure of the valve 39 in regulatmg the flame. On the outer end of the lever 43 is a hand lever 53 on a shaft or pin 54 turning in the outer end of the lever 43. On said shaft is also a toothed sector 55 from which a weighted arm 56 extends, said arm 56 having a hole 57 or other means to connect with a regulat- 1ng chain or wire running to any convenient polnt for actuatlng the lever 43. The outer end of the spring 48 is adapted to variously engage the sector 55 for holding the weighted arm 56 in given position, for the desirable setting of the lever 43 and valve 39 during the atomizing and when connected with a chain regulator (not shown). Lever 53 has a trip arm 53 adapted to displace the spring 48 to variously engage it with sector 55. We would here state that the valve 39 serves to determine the quantity of steam issuing from the steam nozzle 29 and regulates the jet relatively to the level of the oil nozzle 34. The fitting 46 is held to the nipple 47 by set screws 58 at opposite sides of said fitting.

For starting the oil burner we provide a gas burner at 59 preferably having two side arms formed each with a series of jet orifices 60 and having an air inlet hole or holes 61 in the tubular shank of said burner.

. jac'ent to the front end of the mixing tube 31 and within the steam generator 23. The burner 15 may be swung into or out of the furnace A for which purpose the clamp 20"" of ipe 20 1S swivelled onthe standard 18 shell 79 to the pipe 91.

and the pipe 10' rising from said standard to the reservoir 18 is turnably mounted in and also connects by. a branch 72 with the,

water space in the steam generator 71. A float 73 in the chamber has its stem 73 provided at the upper end with a cone-valve 74, seating in a central passage in a disk 75 held by a union 76 in the branch pipe. 72 leading from the top of chamber 70. From the outlet pipe 7 2 at the top leads a steam pipe 77 which extends downwardly and passes laterally as at 78 through the shell or casing 79 of the generator 71, the steam entering a coil 77 for super-heating and passing throughthe pipe 80 which connects as at 26 with the fuel heater 27 corresponding essentially with the fuel heater 27 and having a fuel inlet 32 at the bottom, the fuel passing to the fuel nozzle 34 and the steam passing from the steam nozzle 29 sothat the two streams pass to the mixing tube to a diaphragm regulator 83 the diaphragm of which hasa. pin 84 hearing against the under side of a lever 85 fulcrumed between its ends on a bracket 86 onthe regulator. The one arm of the] lever 85 is Weighted as at85 and the opposite end is adapted to be connected at 87 with a wire 88 running downwardly through the top of the shell 79 on which wire is suspended a damper 89 closing the hole centrally of the generator 71 at the top. The lifting of the damper 89 permits hot products from the furnace 81'to pass from the smoke pipe 90 into the combustion pass downwardly in the interior Y of the generator 81 and upwardly between the double walls of said generator and the The lever 85 connects also by a wire 92 with the handle 93 of the gas cock supplying the burner 94 beneath the heating coil 79. The water pipe 72 entering the bottom of the chamber 70 connects with the pipe 72" fromv the elevated tank 72. In the pipe 72 is a check valve 95 (Figures 8 and 12) the hinged flap or valve proper 96 of which has a small orifice 97 for the passage of water to the chamber 70. Undue steam pressure in the chamber will open the check valve 96 and permit the water to be forced back into the tank 72. The gas burner 59 is supplied by a gas pipe 63" which connects also with the burner 94, said pipe 63 being connected as at 63 with a as supply pipe not shown.

he pipe 80 has a flexible section 80 which is secured at one end to a clamp 80 turnably mounted on standard 18. The gas pipe 63 has a flexible section 63 and the gas pipe 63 has a flexible section 63". Thus the burner may be swung to or from a position at the furnace door B.

For regulating the flow of 011 mto the reservoir 18 the oil pipe 18 lead through a flanged'bushing 98 and within the reservoir and threaded onto .said bushing 1s a threaded ca 99 presenting a seat 100 for a valve 101. he stem 102 of valve 101 extends through the top of the reservoir 18 and it passes through a sleeve 103 carrying a float 103", the sleeve operating through a stufling box 104 in the top of the reservoir 18 in response to the rise andfall of the oil level.

Above sleeve 102 a cam 105 is pivoted at one end to the stem 102 and secured at its opposite end by a slot and pin connection to a clamp bracket 106, there being a slot 107 in said bracket and a pin 108 passing through: said slot into said bracket. The

bracket 106 is secured to a post 109 on reservoir 18, a clamp-screw, 110 on said clamp bracket serving to adjust its height on the post 109. The cam 105 is manually operable to regulate the opening in the valve seat 100 by regulating the distance between the-float V 103 and the valve 101. The sleeve 103 fits friction tight on the stem 102 so that the stem will rise or fall with the float, but the friction can be overcome by "the pressure of the cam 105 on the sleeve when the cam is rocked on its pivot We would state in conclusion that while the illustrated examples constitute practical embodiments of our invention, we do not limit ourselves strictly to the mechanical details herein illustrated, since manifestly the same can be considerably varied without departure from.the spirit of the invention as defined in the appended claims.

Having thus described our invention, we
